How would you redesign the human reproductive system if given the opportunity?

I’ve always wondered what it’d be like if the respective sexes gave birth to the same sex offspring. Like two people get intimate with the desire for a child and wait to see who gets pregnant to see if it’s a boy or a girl. If the man gets pregnant, it’s a boy and if the woman gets pregnant, it’s a girl 😀😀 Equality of the sexes! Woohoo!
